It depends on what type of caterpillar you are talking about. For instance, the woolly bear (or worm) stays in its cocoon from an average of ten to fifteen days. There are oth â¦ er ranges, of course, but that is because woolly bear caterpillars are so common throughout the world.
Temperature is the measure of the average kinetic energy of the molecules in a substance.
Molecules in a substance slow down when a substance is cooled. Temperature is the measure of average kinetic energy of particles. Kinetic energy is the energy of motion. So wh â¦ en temperature decreases, the average kinetic energy decreases, so the energy of motion decreases, and the molecule slows down.
